A collection of random, Pok'emon related gags and short comics.
Open to as many people as want to join. :3 Authors can update as frequently or as rarely as they want. Sprites are welcome. All I ask is that you be able to draw Pok'emon well enough to be somewhat recognizable xD
Keep it PG-13 or lower, kthnx.

In the Manga (Which is radically different from the Anime), it shows pictures of semi-transparent tops, the red part. This way Red could tell who he was sending out, ect. Though I don't know how he'd tell them apart otherwise....

The closest I've seen to labeling was when one of the "one-season sub-rivals" had marks/symbols on his pokeballs. Granted, you still couldn't tell who was in which, but at least he knew that the pokeballs were his.

I have a theory, all trainers have a chip intheir brain and all pokeballs have a chip in them, when you capture a pokemon the pokeball chip downloads the data of that pokemon and sends said data to the trainers brain, so they always know what pokemon is in which pokeball
